| ABSTRACT: In this study, it was evaluated the effect of shade on forage yield, rate of CO2 assimilation, and the quality of annual ryegrass ( Lolium multiflorum L.) cv. 'BRS Ponteio' and black oat ( Avena strigosa Schreb) cv. 'IAPAR 61', grown under three shading conditions (0%, 25%, and 50% shade) using slatted wooden structures. The experimental design was completely randomized with four replications. Slatted structures were efficient in simulating the proposed shading conditions. Shading plants significantly decreased forage yield and CO2 assimilation by both species. Ryegrass cv. 'BRS Ponteio' performed better under shade, with higher forage production under all shading conditions. Rate of CO2 assimilation was reduced by 13 and 22 percentage points... |

| The baru (Dipteryx alata Vog.) is a native species of Brazilian cerrado, and has been widely used in reforestation, medicine, and food industry. The effects of shading levels, reflective material, and seeding depth on the growth of baru seedlings were investigated in this study. The seedlings were grown in full sunlight, and in three production nurseries constructed with 18%, 30%, and 50% shading screens on growing benches coated or not coated with a reflective material (Aluminet®). The seeds were sown at depths of 2.0 or 4.0 cm in black polyethylene bags of 15.0 × 25.0 cm (1.8 L), filled with substrate formulated from the mixture of sandy soil: bovine manure: vermiculite (5: 3: 2). Each seedling production environment was considered an experiment because... |
